Thermochemical treatment of spent coffee grounds via torrefaction: A statistical evidence of biochar properties similarity between inert and oxidative conditions

Results in Engineering, Journal Year: 2024, Volume and Issue: 21, P. 102012 - 102012

Published: March 1, 2024

This study used several statistical analyses to explore the impact of both inert and oxidative conditions on characteristics biochar derived from torrefaction spent coffee grounds (SCG). The also considered variations in temperature residence time. Various fuel were conducted, including high heating value (HHV), index, proximate characteristics, thermogravimetric analysis (TGA), hygroscopicity, Fourier-transform infrared spectroscopy (FTIR). variance (ANOVA) revealed that influence HHV mass yield was insignificant (p ≥ 0.05). Moreover, considering same time, principal component (PCA) hierarchical cluster (HCA) identified belonging group or cluster. finding indicated neither atmospheric condition significantly affected measured this research. Therefore, offers significant advantages as it can produce comparable quality under conditions.

Kinetic and thermodynamic behavior of co-pyrolysis of olive pomace and thermoplastic waste via thermogravimetric analysis

Renewable Energy, Journal Year: 2024, Volume and Issue: 230, P. 120880 - 120880

Published: June 26, 2024

This work represents the first attempt to analyze kinetics, thermodynamics and reaction mechanism of olive pomace (OP) waste plastic materials (PM) co-pyrolysis. Among PM, polypropylene (PP), polystyrene (PS), high density (HDPE), polyvinyl chloride (PVC) poly (ethylene terephthalate) glycol (PETG) were selected. Non-isothermal TG experiments carried out under inert conditions at four heating rates, namely 5, 10, 20 40 °C/min. The kinetic triplet for raw their blends was determined using Starink, Kissinger-Akahira-Sunose Ozawa-Flynn-Wall iso-conversional models. Pyrolysis reactions explained by diverse models, depending on thermal degradation progress. Results shown that co-pyrolysis followed a complex multi-step mechanism. A synergistic effect detected during OP/PM mixtures. addition 50 % (w/w) OP biomass PM decreased energy activation (Ea) from 25 all blends, except PVC/OP. Thermodynamic analysis reveals adding generally reduces barrier (ΔH), PS-OP, improves efficiency (ΔG) facilitating radical formation molecular chain cleavage. As conclusion, this study may open up new avenues valorization resource recovery. Thus, it contribute transition towards circular sustainable economy, through zero goal.

Molecular and Cellular Effects of Microplastics and Nanoplastics: Focus on Inflammation and Senescence

Cells, Journal Year: 2024, Volume and Issue: 13(21), P. 1788 - 1788

Published: Oct. 29, 2024

Microplastics and nanoplastics (MNPs) are ubiquitous environmental contaminants. Their prevalence, persistence, increasing industrial production have led to questions about their long-term impact on human animal health. This narrative review describes the effects of MNPs oxidative stress, inflammation, aging. Exposure leads increased reactive oxygen species (ROS) across multiple experimental models, including cell lines, organoids, systems. ROS can cause damage cellular macromolecules such as DNA, proteins, lipids. Direct interaction between immune cells or an indirect result stress-mediated may lead pro-inflammatory cytokines throughout different MNP-exposure conditions. inflammatory response is a common feature in pathogenesis neurodegenerative, cardiovascular, other age-related diseases. also act senescence inducers by promoting mitochondrial dysfunction, impairing autophagy, activating DNA responses, exacerbating aging altogether. Increased reproductive transfer MNPs/induced damages from parents offspring animals further corroborates transgenerational health risks tiny particles. aims provoke deeper investigation into notorious these pervasive particles well-being longevity.
